BIGdsPIC6 Development System
16.0.
The logic state of all microcontroller input pins may be changed by means of push buttons. Jumper J13 is used to determine the logic
state to be applied to the desired microcontroller pin by pressing appropriate push button. The function of the protective resistor is to limit
the maximum current, thus preventing the development system and peripheral modules from being damaged in case a short circuit oc-
curs. If needed, advanced users may shorten such resistor using jumper J12. Right next to the push buttons, there is a RESET button
which is not directly connected to the microcontroller pin. The reset signal is generated by the programmer.
By pressing any push button when jumper J13 is in the VCC position, a logic one (5V) will be applied to the appropriate microcontroller
pin, as shown in Figure 16-2.
